What is IEC 60335-3-5 ?

IEC 60335-3-5: Safety-Related Parts of Household and Similar Appliances

The International Electrotechnical Commission (IEC) is a global organization that develops and publishes standards for electrical and electronic technologies. One of the most widely-used standards within this organization is IEC 60335-3-5, also known as the "Safety-Related Parts of Household and Similar Appliances" standard. This standard was developed to establish safety requirements for electrical appliances commonly used in homes, such as washing machines, dryers, and refrigerators.

IEC 60335-1: General Requirements for Household and Similar Appliances

Another important standard published by the IEC is IEC 60335-1, also known as the "General Requirements for Household and Similar Appliances" standard. This standard serves as the overarching guide for the design, manufacture, and testing of electrical appliances commonly used in homes. It sets out the general requirements for the safety, electrical performance, and environmental aspects of these appliances.

Key Elements of IEC 60335-1

The IEC 60335-1 standard is divided into several parts, each of which covers a specific aspect of the appliance's design or performance. These parts include:

"Principles of Safety" - This part sets out the general principles and requirements for the safety of the appliance.

"Enclosure" - This part specifies the design and construction of the appliance's enclosure to ensure its safety.

"Power Supplies" - This part sets out the requirements for the power supply to the appliance, including the voltage, frequency, and power efficiency.

"Wiring" - This part specifies the wiring requirements for the appliance, including the number, configuration, and wiring materials.

"Materials and Substances" - This part sets out the materials and substances that are allowed to be used in the construction of the appliance.

"Testing" - This part specifies the testing requirements for the appliance, including the testing methods and procedures.

Conclusion

IEC 60335-3-5 and IEC 60335-1 are important standards that ensure the safety of electrical appliances commonly used in homes. By following the guidelines and requirements set out in these standards, manufacturers can design and manufacture products that are safe, reliable, and meet the needs of their customers.
